AI agents use plan_trip to create or modify resources in Award Travel Finder. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call plan_trip repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Award Travel Finder.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

It is categorised as a Write tool in the Award Travel Finder MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Award Travel Finder MCP server in PolicyLayer and add a rule for plan_trip: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Award Travel Finder. Nothing to install.
plan_trip is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the plan_trip rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for plan_trip. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
plan_trip is provided by the Award Travel Finder MCP server (https://mcp.awardtravelfinder.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
